Dr. NoVo Analyst · Closing Bell Synopsis

BOTTOM LINE: Equities staged a resilient afternoon recovery as retreating bond yields spurred a broad short squeeze, though all three major indices remain locked in an amplifying negative-gamma regime heading into Friday. THE RECAP The session began with heavy selling as surging benchmark Treasury yields pressured valuations, driving SPY to an intraday flush below its prior-day low of 762.20 and pre-market low of 761.93. The tape staged an aggressive midday reversal as yields backed off session peaks, allowing buyers to drive SPY back to 764.64, through its opening-range low of 763.21. Performance converged into the close: tech (QQQ $742.92) and small caps (IWM $279.43) swept higher alongside broad equities to secure positive finishes, turning early distribution into a decisive afternoon short squeeze. DEALER POSITIONING Market makers ended the day positioned in negative gamma across all three complexes: SPY, QQQ, and IWM alike. In this regime, dealers are forced to sell weakness and buy strength; hedging mechanics accelerate price extensions rather than cushion them. The broader public options book maintains a net-long delta posture, tempered by daily theta burn, meaning any loss of upside momentum leaves the tape vulnerable to rapid structural unwinds if dealer buying stalls. TOMORROW'S SETUP For SPY, holding support at 763.21 and 762.20 is vital to keep the squeeze intact and challenge resistance at 765.33, 765.63, and 766.08; a break back below 761.93 exposes the 760.00 put wall to downside acceleration. For QQQ and IWM, watch whether follow-through buying can push spot prices past their upper gamma thresholds to restore dealer dampening, or if negative gamma reignites volatility across the board.

FLOW DYNAMICS Charm — in a negative-gamma regime decay didn't pin, so moves could extend into the close rather than settle. Vanna — with dealers short gamma, a drop in vol would ease the amplification and let the tape settle. Second-order dealer flow context.
